doing a head gasket for a buddy, the head he got worked is from an 85 22r but the block is an 86, using the 86 chain it goes on like a SBC chain with no slack, i know the 84-85 timing chains are 2 links longer, but has anyone else had to use the longer chain when doing 22re block to 22r head, or am i an idiot and missing something small to make it work?
 
The only differences are in the block, tall and short blocks. I can't remember what year it changes and what works with what.......You just need a chain for the 86' block
 
the chain for the 86 is the one that has no slack when i put it on, i found on pirate that there is a difference in like 82 22r heads but the 84-85 heads are the same as the 22re ones except the exhaust ports, thats why im stumped i see no way that the chain shouldnt work but it has no slack at all
 
do you have the guides installed correctly? metal backed?
if so there are two holes in the passenger side guide.
it's possable that you used the wrong hole. i've done
it myself--hope that will help ya.

dawg
 
there just the plastic guides but the chain is tight that i cant even intalle them or the tensioner, i order the longer chain that goes on the 84-85 heads, its 2 links longer so i hope this will work
 
The 84 head and engine is different from the 85. 81-84 ran a dome top piston engine and the 85-95 was a flat top piston engine. The 81-84 head will have round exhaust ports with small holes directly over the big holes. The 85-95 will have both holes integrated together kinda shaped like a pear. Make sure you have the right head for your block as the older head has a cutaway for the dome top pistons to clear, giving it a lot bigger combustion chamber.
 
yeah the guys from pirate told me it wouldnt work kinda sucked i got some false info from someone saying that as long as it has the efi bolt pattern on the intake side of the head it would work on the 22re blocks but that is not the case so i have a 22r head that has been reworked for sale if anyone needs one
